The purpose of this legislation, known as the OASIS Act of 2026, is to enhance the United States' air and missile defense capabilities, particularly in the Middle East. It aims to improve the acquisition process for defense systems and ensure better collaboration with international partners to protect U.S. nationals and assets, as well as those of allied countries. Key provisions of the Act require the Secretary of Defense to conduct a thorough assessment of current air and missile defense systems and interceptors used by the U.S. and its partners in the region.
